Auto-oscillation threshold and line narrowing in MgO-based spin-torque oscillators
S. Cornelissen, L. Bianchini, G. Hrkac +7
We present an experimental study of the power spectrum of current-driven magnetization oscillations in MgO tunnel junctions under low bias. We find the existence of narrow spectral…
Temperature dependence of nonlinear auto-oscillator linewidths: Application to spin-torque nano-oscillators
V. S. Tiberkevich, A. N. Slavin, Joo-Von Kim
The temperature dependence of the generation linewidth for an auto-oscillator with a nonlinear frequency shift is calculated. It is shown that the frequency nonlinearity creates a…
Lineshape distortion in a nonlinear auto-oscillator near generation threshold: Application to spin-torque nano-oscillators
Joo-Von Kim, Q. Mistral, C. Chappert +2
The lineshape in an auto-oscillator with a large nonlinear frequency shift in the presence of thermal noise is calculated. Near the generation threshold, this lineshape becomes str…
Current-driven vortex oscillations in metallic nanocontacts
Q. Mistral, M. van Kampen, G. Hrkac +6
We present experimental evidence of sub-GHz spin-transfer oscillations in metallic nano-contacts that are due to the translational motion of a magnetic vortex. The vortex is shown…
Microwave power generated by a spin-torque oscillator in the presence of noise
Vasil Tiberkevich, Joo-Von Kim, Andrei Slavin
An expression for the microwave power generated by a spin-torque oscillator in the presence of thermal noise is derived. This expression, when used in a subcritical regime, demonst…
Generation linewidth of an auto-oscillator with a nonlinear frequency shift: Spin-torque nano-oscillator
Joo-Von Kim, Vasil Tiberkevich, Andrei N. Slavin
It is shown that the generation linewidth of an auto-oscillator with a nonlinear frequency shift (i.e. an auto-oscillator in which frequency depends on the oscillation amplitude) i…
